I just came across this presentation by Marc Mézard, explaining what I called a year ago a stunning development. It is interesting in that it provides some support for the paper in regards to the explanation of the Belief Propagation (or now AMP) algorithm.
The presentation is at videolectures and is entitled: Occam's razor in massive data acquisition: a statistical physics approach, Also, you may recall two postdoc announcements from that group.
With this cavity explanation, I wonder if these recent invisibility cloaks could not provide a way to physically implement those cavity measures, oh well....
